L. (AxorLOLEjEUXEv) herpestica, Hep. Am. et And. 



In L. Jiliformi aliisque hepaticis sparsim hospitans. 



This very curious hepatic was found only once by myself, 

 in very small quantity, but fertile, on the upper Rio Negro. In 

 Bolivia, however, it was gathered by Dr. Rusby at all his stations, 

 growing sparingly, intermixed with other hepatics, and always 

 sterile.
